Time / space: design one message for three durations

Give students one message and three durations: two seconds, twenty seconds, and two minutes. Each duration must use the same core information but can change scale, sequence, density, and medium.

The two-second version tests recognition. The twenty-second version tests hierarchy and a complete action. The two-minute version tests whether detail rewards continued attention. Students must define the viewing place and distance for each version.

During critique, do not place all versions on a table at once. Recreate the duration and viewing condition. Record what viewers recall, what action they infer, and where they hesitate.

Revision begins with the weakest transition between durations. The aim is not to add more information. It is to decide what becomes available, and when.
